Definitions

  • a heating/ventilation/air conditioning (HVAC) system includes a duct assembly for transferring conditioned air to various locations.
  • HVAC heating/ventilation/air conditioning
  • an HVAC of a vehicle includes a duct assembly for transferring conditioned air into various locations of the vehicle cabin.
  • the duct assembly may include ducts that extend from the engine compartment into the interior of the vehicle through an instrument panel, floor, etc., of the vehicle and/or may include ducts that extend from a rear auxiliary HVAC module.
  • Stationary ducts e.g., headliner ducts, may also extend through a headliner of the vehicle to deliver conditioned air to vents in the headliner.
  • Connecting ducts may connect ducts in lower areas of the vehicles, e.g., the instrument panel, rear auxiliary HVAC module, etc., to the ducts in the headliner to transfer the conditioned air to the ducts in the headliner.
  • the connecting ducts may be, for example, pillar ducts, i.e., ducts within the pillars of the vehicle such as the A-pillar, B-pillar, C-pillar, and D-pillar
  • the pillar ducts are assembled at a later stage in the assembly process after the interior components that house ducts in the lower areas have been installed into the vehicle, and after the headliner has been installed into the vehicle. Since the interior components and the headliner are already installed in the vehicle, these interior components and headliner create packaging constraints that limit the direction in which the pillar ducts may be moved within the vehicle during the assembly process.
  • the packaging constraints may prevent the pillar ducts from being connected to the headliner in a direct vertical direction or from a direct side-loading direction.
  • the pillar ducts may be required to be moved in various directions during assembly. This increases the complexity of the assembly process by requiring fine manipulation of components to make the connection and raises the likelihood of damaging the headliner duct and/or the pillar duct.
  • foam may be used to seal around the pillar duct and movement of the pillar duct in various directions during assembly may inadvertently damage the foam by wrinkling or tearing the foam, or displacing adhesive that holds the foam in place.
  • FIG. 1 is a perspective view of a connecting duct, a stationary duct, and a joint, before the connecting duct is assembled to the stationary duct and the joint;
  • FIG. 2 is a perspective view of the connecting duct inserted into the stationary duct and being engaged with the joint;
  • FIG. 3 is a perspective view of a second end of the connecting duct being engaged with the joint
  • FIG. 4 is perspective view of the second end of the connecting duct engaged with the joint
  • FIG. 5A is a cross-section of the joint showing the connecting duct being engaged with the joint
  • FIG. 5B is a cross-section of the joint showing a ramped surface of the second end of the connecting duct engaging a ramp of the joint for guiding the second end of the connecting duct into the joint;
  • FIG. 5C is a cross-section of the joint with the second end engaged with the joint.
  • FIG. 6 is a perspective view of the second end of the connecting duct being engaged with the joint with a seal mounted to the joint.
  • HVAC heating/ventilation/air conditioning
  • the HVAC system may be the HVAC system of a vehicle (not shown).
  • the HVAC system may be the HVAC system of a stationary structure such as a building.
  • the duct assembly 10 includes a joint 12 and a stationary duct 14 .
  • a connecting duct 16 extends between a first end 18 and a second end 20 spaced a distance D from the first end 18 .
  • the stationary duct 14 and the connecting duct 16 are for a vehicle.
  • the stationary duct 14 is shown as a headliner duct, identified with reference numeral 14
  • the connecting duct 16 is shown as a pillar duct, identified with reference numeral 16 .
  • the pillar duct 16 defines an orifice 22 extending between the first end 18 and the second end 20 .
  • the pillar duct 16 includes a semi-circular surface 24 at the second end 20 extending about a radius R having the same length as the distance D between the first end 18 and the second end 20 .
  • the first end 18 may be inserted into the headliner duct 14 , as shown in FIG. 2 , and the pillar duct 16 may be rotated about the first end 18 to engage the second end 20 with the joint 12 , as shown in FIGS. 3 and 4 .
  • the second end 20 may be swung into engagement with the joint 12 .
  • the radius R of the semi-circular surface 24 provides clearance between the semi-circular surface 24 and the joint 12 when the second end 20 is swung into engagement with the joint 12 , and allows for gradual engagement between the second end 20 and the joint 12 as the second end 20 is swung into the joint 12 , as set forth further below.
  • the joint 12 includes a mating surface 26 .
  • the mating surface 26 receives the joint 12 , as shown in the progressive movement in FIGS. 5A-C , and abuts the semi-circular surface 24 when the second end 20 engages the joint 12 , as shown in FIG. 5C .
  • the mating surface 26 defines an orifice 28 , as shown in FIG. 3 .
  • the orifice of the mating surface 26 is aligned with the orifice 22 of the pillar duct 16 when the second end 20 of the pillar duct 16 is engaged with the joint 12 .
  • Conditioned air from the HVAC system may be forced through the orifice 28 of the mating surface 26 and the orifice 28 of the pillar duct 16 .
  • the conditioned air may be forced from the joint 12 , through the pillar duct 16 , and into the headliner duct 14 .
  • the duct assembly 10 may include a seal 30 disposed on the second end 20 of the pillar duct 16 and/or seal 30 on the mating surface 26 of the joint 12 .
  • the seal 30 is shown on the second end 20 in FIGS. 1-5C .
  • the seal 30 is shown on the mating surface 26 of the joint 12 .
  • the seal 30 may be of any suitable type.
  • the seal 30 may be foam, an elastomeric gasket, etc., attached to the second end 20 and/or the mating surface 26 .
  • the seal 30 may be formed of a material softer than the material of the second end 20 and/or mating surface 26 and may be integrally formed with the second end 20 and/or mating surface 26 , e.g., by a two-shot molding process.
  • the seal 30 seals between the semi-circular surface 24 and the mating surface 26 .
  • the seal 30 is resiliently compressible, and the semi-circular surface 24 and the mating surface 26 compress the seal 30 therebetween when the second end 20 is engaged with the joint 12 .
  • the seal 30 may define an opening 32 aligned with the orifice 28 of the mating surface 26 and the orifice 22 of the pillar duct 16 .
  • the seal 30 extends around a periphery of the orifice 26 of the mating surface and the orifice 22 of the pillar duct 16 to seal about the periphery.
  • the mating surface 26 may extend about the radius R. In other words, a curvature of the mating surface 26 may match a curvature of the second end 20 of the joint 12 . As such, the likelihood of damaging the seal 30 when the second end 20 is engaged with the joint 12 is reduced. For example, in the configuration shown in FIGS. 1-5 with the seal 30 on the second end 20 , as the second end 20 is inserted into the joint 12 during assembly, the seal 30 on second end 20 gradually approaches the mating surface 26 to gradually compress the seal 30 between the second end 20 and the mating surface 26 . This gradual compression reduces the likelihood of damaging the seal 30 , e.g., wrinkling the seal 30 , unseating adhesive between the seal 30 and the second end 20 , etc., during engagement of the second end 20 and the joint 12 .
  • the pillar duct 16 includes a tube 34 presenting the first end 18 and a connecting head 36 presenting the second end 20 .
  • the connecting head 36 engages the joint 12 .
  • the connecting head 36 releasably engages joint 12 .
  • the joint 12 defines a track 38 that receives the second end 20 of the pillar duct 16 , e.g., the connecting head 36 .
  • the connecting head 36 of the pillar duct 16 include a flange 40 extending from the semi-circular surface 24 toward the first end 18 and the track 38 receives the flange 40 , as shown in FIGS. 4-5C .
  • the track 38 includes a wall 42 and a ledge 44 extending transversely the wall 42 . In cross-section, the ledge 44 may extend in parallel to the mating surface 26 for trapping the flange 40 of the pillar duct 16 between the ledge 44 and the mating surface 26 , as shown in FIGS. 4 and 5C .
  • the pillar duct 16 may include two flanges 40 spaced from each other and the track 38 may include two walls 42 /ledges 44 for receiving the flanges 40 , respectively.
  • the track 38 may extend from an open end 46 to a closed end 48 , as identified in FIG. 3 , for example. As shown in FIGS. 3-5C , the track 38 receives the second end 20 of the pillar duct 16 in the open end 46 , and the second end 20 is moved toward the closed end 48 to engage the second end 20 with the joint 12 .
  • the flanges 40 of the second end 20 of the pillar duct 16 narrow from the open end 46 toward the closed end 48 .
  • the semi-circular surface 24 extends from a leading end 50 to a trailing end 52 and the flanges 40 widen in a direction along the semi-circular surface 24 from the leading end 50 to the trailing end 52 .
  • the track 38 narrows from the open end 46 to the closed end 48 .
  • the shape of at least a portion of the track 38 may match the shape of at least a portion of the flanges 40 .
  • One of the track 38 and the flange 40 defines a slot 54 and the other of the track 38 and the flange 40 presents a tab 56 engaged with the slot 54 when the second end 20 is engaged with the joint 12 .
  • the ledge 44 of the track 38 defines the slot 54 .
  • the tab 56 may be near the trailing end 52 of the flange 40 and the slot 54 may be near the open end 46 of the track 38 . As such, as the second end 20 is seated in the joint 12 , the tab 56 engages the slot 54 to lock the second end 20 to the joint 12 .
  • the tab 56 is sized to slide along the ledge 44 as the connecting head 36 is inserted into the joint 12 and, as shown in FIG. 5C , is sized to extend through the slot 54 when the second end 20 is seated in the joint 12 .
  • the wall 42 and/or ledge 44 of the track 38 may be resiliently flexible so that the wall 42 and/or ledge 44 may be selectively flexed away from the tab 56 to disengage the slot 54 from the tab 56 to allow the second end 20 to be disengaged from the joint 12 .
  • the wall 42 and/or ledge 44 of the track 38 may be formed, for example, of plastic.
  • the second end 20 and the joint 12 include two tabs 56 and corresponding slots 54 , as shown in the figures. Alternatively, the second end 20 and the joint 12 may include any suitable number of tabs 56 and slots 54 .
  • the track 38 defines a ramp 58 at the closed end 48 for guiding the second end 20 into the track 38 while minimizing the likelihood of damaging the seal 30 , e.g., wrinkling the seal 30 , unseating the adhesive of the seal 30 , etc.
  • the pillar duct 16 defines a ramped surface 60 extending from the semi-circular surface 24 .
  • the ramped surface 60 is spaced from the seal 30 as the leading end 50 of the connecting head 36 is initially introduced into the open end 46 of the track 38 of the joint 12 .
  • the ramped surface 60 abuts the ramp 58 as the second end 20 is further inserted into the joint 12 .
  • the second end 20 and the mating surface 26 may be configured to position the mating surface 26 spaced from the seal 30 until the ramped surface 60 abuts the ramp 58 to reduce the likelihood of damaging the seal 30 during insertion of the second end 20 into the joint 12 .
  • the ramp 58 forces the second end 20 to rotate, e.g., clockwise in FIGS. 5B and 5C , to clamp the second end 20 against the seal 30 and the mating surface 26 .
  • the ramped surface 60 remains spaced from the seal 30 during much of the insertion of the second end 20 into the track 38 and, when the ramped surface 60 contacts the seal 30 , the ramp 58 guides the ramped surface 60 to clamp the seal 30 between the second end 20 and the mating surface 26 with minimal lateral movement of the ramped surface 60 relative to the seal 30 . This clamping motion with minimal lateral movement reduces the likelihood of damaging the seal 30 during insertion of the second end 20 into the joint 12 .
  • the ramped surface 60 abuts the ramp 58 of the track 38 when the second end 20 of the pillar duct 16 is engaged with the joint 12 .
  • the engagement of the ramped surface 60 and the ramp 58 when the second end 20 is seated in the track 38 pinches the seal 30 between the second end 20 and the mating surface 26 .
  • the ramped surface 60 of the second end 20 extends from the leading end 50 in a direction away from the leading end 50 .
  • the ramped surface 60 extends transversely from the semi-circular surface 24 in a direction away from the leading end 50 .
  • the ramped surface 60 extends at an obtuse angle relative to the trailing end 52 .
  • the connecting duct 16 may be pushed toward the joint 12 to compress the seal 30 and disengage the tab 56 from the slot 54 .
  • the second end 20 may be swung out of the joint 12 .
  • the wall 42 and/or ledge 44 of the track 38 may be resiliently flexible so that the wall 42 and/or ledge 44 may be selectively flexed away from the tab 56 to disengage the slot 54 from the tab 56 to allow the second end 20 to be disengaged from the joint 12 .
  • the HVAC system may, for example, include a rear auxiliary HVAC module, which may be located in a rear of the vehicle.
  • the joint 12 and the headliner duct 14 may extend be located in a rear of the vehicle adjacent the D-pillar of the vehicle, and the pillar duct 16 may extend from the joint 12 to the headline duct along the D-pillar.
  • the joint 12 may be, for example, an extension of the rear auxiliary HVAC module.
  • the joint 12 , rear headliner duct 14 , and pillar duct 16 may, alternatively, be disposed at any pillar of the vehicle.
